The welding head 220 is movably mounted on the mounting plate 210. One end of the welding head 220 away from the mounting plate 210 movably extends into the feeding channel 110. The welding head 220 is used to weld the nickel sheet.

[0025] It should be noted that the bottom plate 100 is a long plate-shaped structure, and the bottom plate 100 is installed on a specific working plane. The first surface of the bottom plate 100 is provided with a feeding channel 110 and a wire feeding channel 120. The feeding channel 110 is arranged along the length direction of the bottom plate 100 and is arranged through the end of the bottom plate 100, so that the nickel sheet is introduced from the feeding channel 110 at one end of the bottom plate 100 and is exported from the other end of the bottom plate 100. The width of the feeding channel 110 is the same as the width of the nickel sheet, and the nickel sheet can be limited and conveyed to prevent the nickel sheet from being skewed during the conveying process. At the same time, the wire feeding channel 120 is arranged on one side of the feeding channel 110, one end of the wire feeding channel 120 is connected to the feeding channel 110, and the other end is arranged through the end of the bottom plate 100, and the wire feeding channel 120 is in accordance with the shape and size of the conductive wire bundle. The small phase is adapted to facilitate the introduction of the conductive wire bundle from the end of the base plate 100 into the feeding channel 110 through the wire feeding channel 120, and to avoid the conductive wire bundle from being offset during the transportation process, so that it can be accurately positioned and overlapped with the nickel sheet and then welded through the welding head 220. In this embodiment, the wire feeding channel 120 and the feeding channel 110 are arranged perpendicular to each other, which can ensure the consistency of the nickel sheet and the wire bundle during welding. The mounting plate 210 is arranged on one side of the base plate 100, and the welding head 220 is movably installed on the mounting plate 210. Through an external driving device, the welding head 220 is driven close to or away from the feeding channel 110, so that the nickel sheet and the conductive wire bundle in the feeding channel 110 can be welded. After welding is completed, the welding head 220 can be driven away from the feeding channel 110, thereby facilitating the loading and unloading of the nickel sheet and the conductive wire bundle.

[0026] Specifically, before welding, the nickel sheet and the wire harness can be respectively transported to the feeding channel 110 and the wire feeding channel 120 by a robot or manually, and aligned after being introduced through the feeding channel 110 and the wire feeding channel 120, and then an external driving device drives the welding head 220 to extend into the feeding channel 110 to weld the nickel sheet and the conductive wire harness. After welding is completed, the welding head 220 withdraws from the feeding channel 110, and then the welded nickel sheet and the conductive wire harness are taken out from the feeding channel 110 by a robot or manually. Since the wire harness is a flexible harness, the conductive wire harness can be taken out together by grabbing the nickel sheet, thereby realizing the welding of the nickel sheet and the conductive wire harness. By providing a bottom plate 100, the bottom plate 100 is provided with a feeding channel 110 and a wire feeding channel 120, and the feeding channel 1 The width of 10 is the same as the width of the nickel sheet to be welded, so that the nickel sheet can be conveyed in a limited position. Similarly, the size of the wire feeding channel 120 is the same as the size of the conductive wire harness to be welded, so that the conductive wire harness can be conveyed in a limited position. The wire feeding channel 120 is connected to the feeding channel 110, so that the nickel sheet and the wire harness are conveyed in a limited position through the feeding channel 110 and the wire feeding channel 120 respectively by manual or external feeding devices, so that the nickel sheet and the wire harness can be conveyed accurately to avoid the skewness of the nickel sheet and the conductive wire harness, and the nickel sheet and the wire harness can be welded accurately.

The welding head 220 is installed above the bottom plate 100, and the driver drives the welding head 220 to approach or move away from the feeding channel 110, so as to realize welding of the nickel sheet and the conductive wire bundle in the feeding channel 110. In this embodiment, the driver adopts a cylinder, which is a commonly used driving device for realizing linear reciprocating motion, has a simple structure, is easy to install, and can drive the welding head 220 to approach or move away from the feeding channel 110.

[0028] In one embodiment, the wire feeding channels 120 are provided in plurality, and each of the wire feeding channels 120 is spaced apart from each other, and each of the wire feeding channels 120 is respectively connected to the feeding channel 110. It can be understood that in this embodiment, a plurality of wire feeding channels 120 are provided, and the plurality of wire feeding channels 120 are spaced apart from each other and arranged in parallel with each other, and each of the wire feeding channels 120 is respectively arranged perpendicular to the feeding channel 110. By providing a plurality of wire feeding channels 120, a plurality of nickel sheets and a plurality of conductive wire bundles can be transported on the feeding channel 110 and the wire feeding channels 120. After uniformly loading each nickel sheet and each conductive wire bundle, each nickel sheet and each conductive wire bundle are welded one by one through the welding head 220. After welding is completed, the nickel sheets and conductive wire bundles that have been welded first can be unloaded according to the welding order. In this way, not only can multiple groups of nickel sheets and conductive wire bundles be welded, but also multiple groups of nickel sheets and conductive wire bundles can be welded. Unified loading and unloading is conducive to improving production efficiency. At the same time, the finished nickel sheets and conductive wire harnesses after welding can be buffered in the feeding channel 110. After all the groups of nickel sheets and conductive wire harnesses on the feeding channel 110 are welded, the groups of nickel sheets and conductive wire harnesses can be discharged in turn. Since the welded nickel sheets and conductive wire harnesses need to be cooled and formed, the welded nickel sheets and conductive wire harnesses can be cooled and formed in the feeding channel 110 before being discharged, so as to avoid discharging the welded nickel sheets and conductive wire harnesses too quickly and shifting the welded nickel sheets and conductive wire harnesses, which is conducive to further improving the quality and reliability of the finished nickel sheets and conductive wire harnesses.

When the nickel sheet is transported to the feeding channel 110, each nickel sheet can be limited by each limiting groove 311 to prevent two nickel sheets from being fed in at the same time. Or more than two overlapping nickel sheets can play an anti-mistake role, thereby ensuring precise welding of a single nickel sheet. Specifically, in this embodiment, the limit blocks 310 are spaced apart from each other, thereby ensuring that a certain gap is left between the limit grooves 311. After each nickel sheet is positioned and sent to each limit groove 311 by a robot or manually, after welding, the nickel sheet is clamped by a robot or manually and moved to the gap between two adjacent limit grooves 311.
